A quality sleeping pad should do two things- protect you from the ground and keep warm air from escaping into the ground. The new Sea to Summit Comfort Plus sleeping pad does both of those things exceptionally well. Using a new dual layer technology the Comfort Plus cushions your body with nearly 550 air cells that act to both disperse body weight over a large area and insulate against the cold ground. The Comfort Plus uses dual layer construction which can be controlled independently with vents for the perfect balance of support and comfort.The result is a remarkably comfortable, warm sleeping pad that wont weigh you down on long hunts in the alpine. The Sea to Summit Comfort Plus- because you can haul your Sleep Number mattress up the mountain.
